 USNM. 1 o\ 27.3; Ambatoloka, Nosy Be, Madagascar; Mme

Diagnosis. — Rostral plate rounded anterolaterally; ocular scales 

 small; telson with 3 pairs of marginal teeth, submedians with movable 

 apices; dorsal surface of telson with numerous spinules and tubercles; 

 uropod with normal setation, margins of endopod, inner portion of 

 proximal segment, and distal segment of exopod fringed with setae. 



Color. — Faded in most specimens; in the male from the Comoro 

 Islands there are median and lateral dark patches on the sixth thoracic 

 somites, a dark patch on the first abdominal somite, traces of a dark 

 band on each abdominal somite, and the ventral surface of the thorax 

 and the copulatory tubes are dark. 



Discussion. — The uropod provided with a normal fringe of setae 

 will immediately distinguish this species and G. spinosus Bigelow 

 from G. demanii Henderson, G. hendersoni Manning, and G. crosnieri 

 Manning. Gonodactylus hendersoni differs from G. spinosus in having 

 the lateral teeth of the telson well developed, projecting, and in 

 having the intermediate denticles recessed anteriorly. 



All of the specimens reported herein have few, large tubercles on 

 the telson. 



Distribution. — Western Indian Ocean from the Red Sea south- 

 ward to South Africa (Manning, 1967b).
